Definitions

  • the present invention relates to an insertion aid for a voice prosthesis comprising a rod-shaped device and further a long-sleeve, as well as their use.

  • the most important remedy here is the voice prosthesis, which is also referred to as a "shunt valve".
  • a voice prosthesis functions of the removed larynx can be replaced.
  • the use of a voice prosthesis allows air to be supplied from the lungs via the esophagus to the pharynx. The exhaled air is used for speaking.
  • the voice prosthesis seals the connection between the esophagus (trachea) and the trachea during the swallowing of food and drinks, whereby the user of the voice prosthesis is protected against an accidental ingestion of the food.
  • the voice prosthesis is designed as an indwelling prosthesis, this is usually used and / or changed by the doctor.
  • Such indwelling prostheses are inserted into what is known as the tracheoesophageal fistula, a surgically created opening between the air and the esophagus.
  • a voice is formed by closure of the tracheostoma with one finger and simultaneous exhalation. In doing so, the valve in the voice prosthesis opens due to the resulting pressure and allows air to enter the esophagus, forming a sound for the language.
